Question

Identify the equation that has a slope of -3 and a y-intercept of -9.

y = 3x + 9

y = -9x - 3

y = 9x + 3

y = -3x - 9

Answer 1

y = -3x - 9

Explanation:

y=mx+b

^ That is the slope intercept form

M - Slope

Y - Y value

X - X value

B - Y intercept

We know that the slope is -3 and the y intercept is -9, so the equation should be:

y = -3x - 9 (The fourth answer)
